城市公共自行车租赁点配置分析与优化

Analysis and Optimization of Rental Points Configuration of Public Bicycle System

针对城市部分公共自行车租赁点自行车利用率低和服务质量不高等问题,提出了基于敏感性分析方法的公共自行车租赁点优化方案。以兰州市公共自行车系统的实际运营数据为依据,根据系统动力学原理,构建基于AnyLogic的公共自行车系统仿真模型,以租赁点的设施利用率和服务度为评价指标,利用敏感性分析和迭代相结合的方法,优化公共自行车租赁点的配车数。最后以公共自行车系统仿真模型为实验平台,对比分析优化前后租赁点的评价指标,为优化城市公共自行车系统提供参考。

In view of the low utilization rate of bicycle and the low quality of service,the method based on the sensitivity analysis is built to optimize the number of assigned bicycle of the public bicycle rental stations.Based on analyzing the operation data of public bicycle rental stations in Lanzhou,a simulation model of public bicycle system based on AnyLogic is constructed according to the system dynamics principle.Then,the facility utilization rate and service degree of the rental stations are used as the evaluation indexes,and the number of assigned bicycle of the rental stations is optimized through the combination of sensitivity analysis and iteration.Finally,the public bicycle system simulation model is used as the experimental platform,and the evaluation indexes of the rental stations before and after optimization are analyzed and compared to offer the reference for the optimization of the urban public bicycle system.
